3 Claims.

This invention relates to anim'proved safety razor which is combined with ablade magazine for the purpose of feeding a ,blade into the razor. The razor and blade are readiIyseparabIe as the razor is used independent of the magazine. vThis type of razor is shown in my Patent No. 1,969,945,

issued August 14, 1934. y

In the present invention I employ means Lfor positioning the magazine on the razor which means also causes the retreat of the back plate i plate is allowed to clamp the blade. This insures easy positioning of the blade and a firm top plate can be used. The blade platform in this form of razor isstiiLrelative to the other blade-clamping parts. f' y su; The invention is illustrated inthe accompanying drawings, in which Figure 1 is an end view,

partly in section, with a blade in shaving position.

`Figure 2 is a similar view withr a blade after injection into the razor and in rear of its shaving position with the finger of a blade 'magazine shown in section. FigureB is a perspective view of the blade magazine. Figure 4 is a longitudinal section of the blade magazine. Figure 5 is a perspective view of a razor shown in Figures 1 and 2 and also showing the extreme end of the iinger of the magazine. Figure 6 is anend lview of a modiiied form of razor with the finger of the magazine in section in the razor. Figure 7 is anv end View of still another modification with the blade in shaving position. Figure 8 is a similar view but with a blade in rear of itsshaving position and showing thefinger of the magazine in section. Figure 9 is a top view -of one end` of v the magazine and the iinger. Figure 10 is a perspective view of the razor shown in Figures '7 and 8 and showing the end of the finger of the magazine. Figure 1'1 is an end view of a modification employing -a cam for positioning the razor blade with the blade in position. Figure 12 is a view similar to Figure 11 with the cam raised alongwith the top plate andY with the finger of the y magazine in section.

In the form of razor shown in Figures 1, 2 and 5, the blade platform I0 is adapted to receive a fblade Il endwise and support it in shaving position, thatgis, with its cutting edge at the proper distance from the guard I2. The stops I3 may installed f o'r preventing 'theh Vbladel from advancingto'o farbut the stops are Vnot essential if the blades are all of the same width. 5

AIn this type of razor a fresh blade is passed linto the razor, from a magazine, in rear of its shaving posiiton. A spring actuated piece -is moved out of the path of the fresh blade when the magazine and razor` aretemporarily' joined. I10 When the magazineis'withdrawn from-the razor the spring-actuated piece is freed and pushes the blade forward into shaving position relative to the guard.

In-the razor shown in Figure 2 the spring actu- 15 ated piece is a plate I4 of spring metal which is secured to the base I5 of the blade platform. The spring I l(has its upper end I6 in rear of the top face of the -blade platform and a part I'I that projects into a recess orslot I8 in .the base I5. 20

zine. The nger 25' projects from the front of the magazine and is preferably tapered as at 26 30 for easy entrance. A back plate 21 is secured to the baseV I5 and is bent over to form a spring top plate 28 that rests on the top of the blade l I.

When a fresh blade isv needed, the iinger 25 is slid into the recess I8. This holds the part in.. 35

alignment and pushes back the springplate I4 as in Figure 2. This spring I4 acts as a guide to the rear edge of the blade I I fed into the razorby sliding the slide 23.- When the blade is inside the razor the. magazine finger 25 is withdrawn 40 and the spring is then free and it pushes the blade into shaving position as shown in Figure l. Thisform of razor is firm as the blade platform I0 is made relatively stiff and the spring therefore moves positively When it is pushed 45 back or released. A suitable .handle 29 is provided for the manipulation of the razor and for holding it when the magazine is attached and operated. In Figure 6 I show a modification in which the back plate 30 and the top plate 3| are 50 used as the springmember. This form utilizes the spring action of the back plate- Without the interposition of an additional spring member. The operation by the finger 25 is the same as in the razor -above described but in this form the 55 pressure by the top plate 3| on the blade, is relieved when the back plate 30 is pushed back by the finger 25.

In Figures 7 to 10, I show a form in which the back. of the blade isreleased but after the top plate is raised and when a fresh blade is inserted and the finger of the magazine withdrawn the operations are so timed that the spring member engages and positions the blade forwardly before the top plate clamps the blade in place. This insures a relatively free blade during the positioning operation and also insures a positive clamping of the blade by the top plate. In this form`of razor 'the blade platform I0 and the guard I2 and the stops ll are substantially the same. The back plate 32 has the overhanging of the top plate 33 for engaging the top face of the blade Il. The back plate has a limited vertical movement. The pins34 on the base I5 projecting through slots 35 in the back plate show one form 5 of a sliding connection. The back plate is held in lowered normal position by a suitable spring. One form is shown by the spring 36 secured to the base I5, extending through the base, and resting in a slit 31 in the back- On the front face of the back plate I show a spring 38 for engaging the back of the blade. This spring is relatively light. The back plate has a suitable stop, such as the bent over part 39 which stop is projected into a recess 4l) in the base I5, this recess receiving the nger of the magazine. The magazine 4I has the finger 42 which has the front end tapered as at 43 which taper is positioned to engage and raise the stop 39 and thus lift the back plate and top plate.

The finger also has a flange 44 with a laterally tapered front end 45 for engaging the positioning spring 38. The projection of the part 43 beyond the flange 44 insures the raising of the back plate before the blade positioning spring is retreated to the positions shown in Figure 8.

For the same reason, when the finger 42 is withdrawn the flange 44 releases the spring 38 when it clears the spring and the spring when so released pushes the blade II forwardly into shaving position. The back plate 32 is still held up however by the part 43 of the finger 42 and when the back plate is finally released the blade is in position. The back plate is pushed down by the spring 35 .and the top plate engages the blade only after the blade is positioned and there is no frictional interference with the blade when it is includes a top plate 49 which is bent over to engage the top face of the blade, a cam portion` and the cam 5 0 pushes the blade II forwardly after which the top plate 49 engages the blade to hold it down against chattering in the shaving operation. Y

Various changes may be made in the form and proportion of the parts Without departing from the scope of the invention as set forth in the claims. y

1. A safety razor comprising a blade platform for supporting a blade, a springmember having a back plate for engaging the back edge of the blade and a spring top plate for bearing lon the top face of the blade, a magazine having a finger for sliding engagement with the razor for holding the magazine in position on the razor, said nger having a surface to engage the spring member for moving both the back plate and the top plate out of normal position while the razor and magazineA are' assembled, said finger being so formed that the back plate is returned to normal position prior to the return of the top plate.

2. A safety razor comprising a relatively stiff blade platform, a back plate for resiliently engaging the edge of a blade on the platform, in combination' with a magazine for blades, a linger on the magazine for sliding engagement between the blade platform and the back plate whereby the'back plate is moved out of its normal position, a stop on the back plate, a top plate extending from the back plate and engaging the top face of the blade, and a surface on the finger for engaging the stop whereby the back plate is raised to relieve the pressure of the top plate on the blade, said stop engaging surface extending on the finger beyond the part that engages the back plate in order to position the blade before the top plate clamps the blade on the withdrawal of the nger.

3. A safety razor comprising a base having a
